It will be seen that by the construction set forth, each gas is delivered in sheet form into the compartment 24, and that there superior opportunity for mixture of the gases, as compared vwith delivery of one or both of the gases into the mixing chamber in a solid Vstream as is usual in Oxy-acetylene torches.

- chamber of my torch, I provide a mixed gas The shell 16 of theY mixing head D contains an internal annular rib 26 surrounding and spaced from the stem 20 of the inner inlet member 20 and serving as ay baiie by which the gases are restrained in their escape from said compartment, thereby facilitatingmixture of the gases.

`It is highly .essential thatthe acetylene and oxygen should be mixed as thoroughly as possible and to provide for more complete mixture than occurs in the mixing conductor leading from the mixing head to the tip head by which Vmore complete admixture is accomplished. 27 designates the shell of the mixed gas conductor which is joined by a coupling 28 to the front end of the mixing head shell 16. The shell 27 is connectedby suitable couplings, such as those 29V and 30, to the tip head E containing a channel 32 into which the mixed gases are delivered. lVithin the shell 27, and preferably insulated therefrom, is a conducting tube 33 which is contracted at intervals to produce throats 34 of lessdiameter than the remainder of the tube` and as the gases pass through these their ovv is Vretarded thereby causing them to be more thoroughly commingled lvvith each other.

The tiphead E is intended for use in my torch when the torch is used for metal cutting operations and itv contains, besides the duct 32, a second duct 35 through which an auxiliary supply of oxvgen may be delivered to the tip ofthe torch. vThe tip of the torch comprises an inner member 36 having a central longitudinal duct 36 therein, and an outer member 37surrounding the inner n, member and spaced therefrom, as seen in Vinner tin member 36.

Fig. IV, said members being of different cross section to furnish ing tothe `outlet 39 vat the outer end of the Additional supply of oxygen-is delivered to the tip headE through an auxiliary sup ply pipe 40 `leading fromx the valve housing 5 in the main oxygen supply pipe to the duct 35 in the tip head E. At the rear end of the auxiliary supply pipe is an annular coupling member 41 which is fitted to the valve housing 5 around the threaded stem 5 at the side of the housing opposite that through which the stem of the valve 6 cxtends. The coupling member 41 is spaced from the threaded stem 5 to provide an oxygen receiving chamber 42, and oxygen entering said chamber from the duct 7 passes therefrom through a duct 43 in the coupling member to the auxiliary oxygen supply pipe. The annular coupling member 41 is held in position against the valve housing 5 by a nut fitted to the threaded stem 5 and havinga seat 45 which engages the outer side of the coupling member 41 to clamp it between said nut and the body of the valve housing 5 around said stem. At the inner end of the nut 44 is a neck 46 which serves to close the duct 7 When the auxiliary supply pipe is disconnected from the torch to adapt thetorch for Welding operations.

47 designates a valve housing in the auxiliary oxygen supply pipe 40. This valve Y housing` contains a valve 48 having a valve stem 49 provided with an operating Wheel 50. The valve 48 serves to control the passage of oxygen to the tip of the torch and it may be operated by direct application of the hand of the user to the operating Wheel 50. It is sometimes necessary to apply the torch to an object to be cut which is at too great a distance from the operator to permit of his grasping the operating Wheel during the cutting operation. We therefore provide for the operation of the said wheel. in such an instance, by furnishing the Wheel 50 with a flanged rim and connect to said' wheel two operating cords 51 and 52 which extend around the Wheel in opposite directions. These cords may be of any desired lengths and by pulling upon them the operator may open and close the valve 48 at Will.

Our torch may be readily suited for Welding operations by removing the auxiliary `oxygen supply pipe 40 and the tip head E With its t1p, and lsubstituting for the latter a tip head having only a single duct into which themixed gas is delivered. Then by applying a Welding jet tip to said head the torch is in condition for Weldingoperations.

We claim 1. In a torch, a head having two gas conducting channels therein leading to the forward end of the head, a mixing chamber shell secured to the forward end of said head, an inner member located centrally Within said shell, said inner member containlying a duct in communication With one of the "channels in said head and extending laterally through the inlet member at a point near its rear end, a ring Within said shell surrounding said inner member and having yio a duct therein communicating with the second channelin said head, said ringbeing spaced from said inner member to provide an inner annular gas conducting channel leading from the duct in said inner linem-y taining a duct in communication withfonel of the channels in said head and extending laterally through the inlet member ata point near its rear end, a ring within said shell surrounding said inner member and `having duct therein con'imunicating with the second channel in said head, vsaid ring being spaced from said inner member .to provide an infrom the duct in said innerinember and being spaced from saidmixing chamberv shell i to provide an outer annular channel through which the gas passing through said ringI may pass to mingle with the vgas passing" from the innerl annular gas conducting channel to the mixing chamber in front'of said ring, saidinner member beingextendedy beyond said ring and being surrounded by an annular baiie serving to retard vthe flow of the mixed gases from the "mixing chamber.

3. In a torch having a tip, the combina-k f tion of gas mixing means having communi- `:housing lin said supply pipe,

mixing' means, a valve housing in said oxygen supply pipe, a v'alvein said housing,

the saidvalve housing having a duct therein lleading tp oneof its sides, andy being 4pro,-
